Russia has been invited by the Syrian government; the United States hasn’t. Russians on the ground in Syria are recognized in international law as there legally. Is mindlessly continuing or increasing the Obama / CIA / Saudi / Israeli / Qatari / Turkish / UAE illegal war against the Syrian people worth this WWIII risk? **** no. Now watch the lunatics currently in the White House, CIA-HQ and Pentagon act more belligerently in response to this warning like the provocating terrorists they are.
